Palo Alto Networks PSE-Strata-Pro-24 Practice Exam Questions & Answers

DNS Security (Answer C):

DNS Security is the appropriate subscription for addressing threats over port 53.

DNS tunneling is a common method used for data exfiltration, infiltration, and C2 activities, as it allows malicious traffic to be hidden within legitimate DNS queries.

The DNS Security service applies machine learning models to analyze DNS queries in real-time, block malicious domains, and prevent tunneling activities.

It integrates seamlessly with the NGFW, ensuring advanced protection against DNS-based threats without requiring additional infrastructure.

Why Not Threat Prevention (Answer A):

Threat Prevention is critical for blocking malware, exploits, and vulnerabilities, but it does not specifically address DNS-based tunneling or C2 activities over port 53.

Why Not App-ID and Data Loss Prevention (Answer B):

While App-ID can identify applications, and Data Loss Prevention (DLP) helps prevent sensitive data leakage, neither focuses on blocking DNS tunneling or malicious activity over port 53.

Why Not Advanced Threat Prevention and Advanced URL Filtering (Answer D):

Advanced Threat Prevention and URL Filtering are excellent for broader web and network threats, but DNS tunneling specifically requires the DNS Security subscription, which specializes in DNS-layer threats.

Reference from Palo Alto Networks Documentation:

DNS Security Subscription Overview

DNS-based threats, such as DNS tunneling, phishing, or malware command-and-control (C2) activities, are commonly used by attackers to exfiltrate data or establish malicious communications. Palo Alto Networks firewalls provide several mechanisms to address these threats, and the correct method is DNS sinkholing.

Why 'DNS sinkholing' (Correct Answer D)?

DNS sinkholing redirects DNS queries for malicious domains to an internal or non-routable IP address, effectively preventing communication with malicious domains. When a user or endpoint tries to connect to a malicious domain, the sinkhole DNS entry ensures the traffic is blocked or routed to a controlled destination.

DNS sinkholing is especially effective for blocking malware trying to contact its C2 server or preventing data exfiltration.

Why not 'DNS proxy' (Option A)?

A DNS proxy is used to forward DNS queries from endpoints to an upstream DNS server. While it can be part of a network's DNS setup, it does not actively stop DNS-based threats.

Why not 'Buffer overflow protection' (Option B)?

Buffer overflow protection is a method used to prevent memory-related attacks, such as exploiting software vulnerabilities. It is unrelated to DNS-based threat prevention.

Why not 'DNS tunneling' (Option C)?

DNS tunneling is itself a type of DNS-based threat where attackers encode malicious traffic within DNS queries and responses. This option refers to the threat itself, not the method to stop it.

Zero Trust is a strategic framework for securing infrastructure and data by eliminating implicit trust and continuously validating every stage of digital interaction. Palo Alto Networks NGFWs are designed with native capabilities to align with Zero Trust principles, such as monitoring transactions, validating identities, and enforcing least-privilege access. The following narratives effectively address the customer's question:

Option A

: While emphasizing Zero Trust as an ideology is accurate, this response does not directly explain how Palo Alto Networks firewalls facilitate mapping of transactions. It provides context but is insufficient for addressing the technical aspect of the question.

Option B: Decryption and security protections are important for identifying malicious traffic, but they are not specific to mapping transactions within a Zero Trust framework. This response focuses on a subset of security functions rather than the broader concept of visibility and policy enforcement.

Option C (Correct): Placing the NGFW in the network provides visibility into every traffic flow across users, devices, and applications. This allows the firewall to map transactions and enforce Zero Trust principles such as segmenting networks, inspecting all traffic, and controlling access. With features like App-ID, User-ID, and Content-ID, the firewall provides granular insights into traffic flows, making it easier to identify and secure transactions.

Option D (Correct): Palo Alto Networks NGFWs use security policies based on users, applications, and data objects to align with Zero Trust principles. Instead of relying on IP addresses or ports, policies are enforced based on the application's behavior, the identity of the user, and the sensitivity of the data involved. This mapping ensures that only authorized users can access specific resources, which is a cornerstone of Zero Trust.

The Best Practice Assessment (BPA) report evaluates firewall and Panorama configurations against Palo Alto Networks' best practice recommendations. It provides actionable insights to improve the security posture of the deployment. BPA reports can be generated from the following locations:

Why 'PANW Partner Portal' (Correct Answer A)?

Partners with access to the Palo Alto Networks Partner Portal can generate BPA reports for customers as part of their service offerings. This allows partners to assess and demonstrate compliance with best practices.

Why 'Customer Support Portal' (Correct Answer B)?

Customers can log in to the Palo Alto Networks Customer Support Portal to generate their own BPA reports. This enables organizations to self-assess and improve their firewall configurations.

Why not 'AIOps' (Option C)?

While AIOps provides operational insights and best practice recommendations, it does not generate full BPA reports. BPA and AIOps are distinct tools within the Palo Alto Networks ecosystem.

Why not 'Strata Cloud Manager (SCM)' (Option D)?

Strata Cloud Manager is designed for managing multiple Palo Alto Networks cloud-delivered services and NGFWs but does not currently support generating BPA reports. BPA is limited to the Partner Portal and Customer Support Portal.

Strata Cloud Manager (SCM), part of Palo Alto Networks' Prisma Access and Prisma SD-WAN suite, provides enhanced visibility and control for managing compliance and security policies across the network. In the Premium version of SCM, compliance frameworks are pre-integrated to help organizations streamline audits and maintain adherence to critical standards.

A . Payment Card Industry (PCI)

PCI DSS (Data Security Standard) compliance is essential for businesses that handle payment card data. SCM Premium provides monitoring, reporting, and auditing tools that align with PCI requirements, ensuring that sensitive payment data is processed securely across the network.

B . National Institute of Standards and Technology (NIST)

NIST is a comprehensive cybersecurity framework used in various industries, especially in the government sector. However, NIST is not specifically included in SCM Premium; organizations may need separate configurations or external tools to fully comply with NIST guidelines.

C . Center for Internet Security (CIS)

CIS benchmarks provide security best practices for securing IT systems and data. SCM Premium includes CIS compliance checks, enabling organizations to maintain a strong baseline security posture and proactively address vulnerabilities.

D . Health Insurance Portability and Accountability Act (HIPAA)

HIPAA is a framework designed to protect sensitive healthcare information. While Palo Alto Networks provides general solutions that can be aligned with HIPAA compliance, it is not explicitly included as a compliance framework in SCM Premium.

Key Takeaways:

The frameworks included in SCM Premium are PCI DSS and CIS.

Other frameworks like NIST and HIPAA may require additional configurations or are supported indirectly but not explicitly part of the Premium compliance checks.
